Operation Modes
IPmux-1 E1/T1
IPmux-1 E1/T1 operation modes are:
Unframed
Fractional
Fractional with CAS.
Unframed
In the transparent mode, the incoming bit stream from each channel (regardless of
framing) is converted into IP over Ethernet frames. This option provides clear
channel end-to-end service (unframed).
Fractional
In the fractional mode, the incoming bit stream is regarded as a sequence of
n x 64 kbps channel groups (according to framing). Each predefined group of
channels is converted into a structure block. The structure block is packetized into
IP frames and transmitted.
This mode allows transmission of several selected timeslots without the whole E1
or T1 frame, as in transparent mode.
Use Fractional mode when grooming ISDN BRI channels from a remote IPmux-1E
unit.
